IMPROVEMENT IN cuLTivAToRs.

Specification forming part of Letters Patent N 136,574, dated March 4, 1873..

To all whom t may concern:

Be it known that I, EDWARD WIARD, of Louisville, in the county ot' Jefferson and State ot' Kentucky, have invented an lmprovementin Uultivators; and l do hereby declare that the following is a i'ull, clear, and exact description thereof, reference being had to the accompanyin g drawing making a part ot' this specitication, in which- Figure l, Plate 1, is a perspective View of the cultivator with three shovels, two of which are in front ot' a single one. Fig. 2, Plate l, is a similar view ot' the same parts with one shovel yarranged in front ot' two. Fig. 3, Plate 2, is a perspective view ot' a single-shovel cultivator. Fig. 4, Plate 2, is a perspective view ot' a double-shovel cultivator. Y

Similar letters ot' reference indicate corresponding parts in the several figures.

The object ot' this invention is to combine in a single hand eultivator such features as will admit of an interchangeability ot' shovels, so that the shovels can be used either singly, in pairs, or in threes, at pleasure, as will be hereinafter explained.

r.lhe following description ot' my invention will enable'others skilled in the art to understand it.

In the accompanying drawing, A represents the beam ofthe cultiva-tor. B B are the handles or stiles, and C are the standards, having affixed to them the shovels g, which may or may not be reversible. The cultivator shown by Fig.l has three shovels attached to it. The rear shovel-standard (l is-arran ged in the same plane as the beam A, and secured to this beam by means of a bolt passed transversely through the beam and through ears Vp on the said standard. This rear standard C is further secured to the beam A by means ot' a brace, c, and a vertical bolt, b, which latter passes through the beam A and through one ot' several holes made-through the brace. The bolt b passes through a post, a, and receives a nut, b', on its upper end. rIhe two front shovel-standards C C are secured to the outer ends of two posts, c e, by means of a long` bolt on the ends ot' which nuts are applied. These front standards C (.l are further secured to the beam A by means of posts c e', braces c c', and a bolt, which latter passes through the posts c e and through the beam A, and receives nuts on its ends. In front of the post a is a similar post, af, which, like the rear post c, is secured to thel bea-m A by means of a bolt, b, and nut b. The shovel-standard C, which, in Fig. 1, is at the rear ot' the beam A, may be applied at the point where the two posts e e ot' the pair of shovel-standards are attached, and these latter may be applied at the rear of the beam A. Such an arrangement is represented by Fig. 2.

In cultivating crops with the cultivator arranged as in Fig. 2 the earth is thrown bythe rear shovels into the furrow made by the front shovel, and trenches or furrows are' left alongside of the plantson either side. With the single-caster shovel in rear, as in Fig. l, the trench or furrow is left at the greatest distance from the plants and the earth is hilled up about their roots. Y

To form a sin gleshovel plow the front stand ards U C are removed, and Fig. is produced. Remove the center standard of Fig. 3 and bolt the other two standards separately to the beam A, one in front ot' the other, as shown in Fig. 4, and a double-shovel cultivator is produced.

In this kind ot1 cultivator the posts c a may be used to set the standards 0E from the beam It will be seen from Athe above description that I obtain a single, a double, or a triple shovel-cultivator, whichever may be required, and use only a single beam; and I so connect the standards to this beam that the different changes can be readily made and the standard or standards, as the case may be, are firmly secured to their beam'.

Having described my invention,what I claim as new, and desire to secure by Letters Patent, 1s-

'lhe cultivator, with the described means for adjustment to carry one, two, or three shovels and to change the same to different positions, as shown in the drawing.
